Robotic Arm-based Antenna Measurement System

Abstract

An in house robotic arm-based antenna measurement system is presented. The need for a flexible measurement system to work at millimeter-wave bands (mmW) is the main motivation of this work. At the moment the system is programmed to perform planar acquisitions of 80mm×80mm up to 67 GHz. Post-processing techniques in order to reduce the effect of the non-anechoic environment and acquisition time have also been implemented. The system has been validated by means of measurements in the K-band with very good agreement with reference measurement performed in a spherical range in anechoic chamber.
